SCALE.

SPECIFICATION forming part of Letters Patent No. 256,502, dated April 18, 1882.

Application filed December 6, 1881.

To all whom it may concern Be it known that I, WILLIAM W.REYNoLDs,

a citizen of the United States, residing in the city of Rutland, county of Butland, and State of Vermont, have invented certain new and useful Improvements in Scales, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates particularly to what are commonly known as platformscales, although one of its features is applicable to any of those scales in which a graduated beam and movable counterpoise are used.

In the use of scales of this construction it is often desirable, when the counterpoise has been adjusted so that the scale will weigh a given amount, to lock it in such adjusted position, so that a large number of packages of the same weight can be made up without danger ofhaving the counterpoise accidentally shifted and the accuracy of the weight destroyed.

This is particularly desirable in those scales which are used when Hour and other like products are weighed and packed in sacks or barrels. It is also desirable that scales which are to be used for this and other like purposes should be provided with a table or shelf to hold the operatois tools and the material used in 0 closing the packages.

By this invention there is provided a convenient, simple, and effective means for so curely holding the counterpoise in any position to which it has been adjusted, and also a convenient table for the scale-weights, the tools of the operator, the material being used, &c.

The invention also consists in certain other details of construction and combinations of parts, all of which will be fully hereinafter de- 0 scribed, and particularly pointed out in the claims.

In said drawings, Figure 1 is an elevation of a platform-scale provided with the hereindescribed improvements. Fig. 2 shows the 5 table in plan and longitudinal section upon the line y 3 Fig. 3 is a side view of a portion of the scale-beam and the counterpoise, the the latter being partly in section to show more clearly the construction of the clamping-screw.

Fig. 4 is a plan view of the clamping-screw.

(No model.)

The scale shown is of the usual construction of platform scales. Its beam at is graduated upon its sides in the usual manner, and is provided with the sliding counterpoise O. The counterpoise is slotted, so as to allow the beam 5 to pass through it, and ismade with an enlarged head, which is cut away at f to give prominence to the index-point 0 and to allow the figures on the beam to be fully disclosed. The part 'i of the counterpoise, which extends below the beam, is in the form of a cylinder, and is screw-threaded, so as to form a female screw, in which works the set-screw H. The set-screw H is provided with the milled head h, by which it can be readily turned, so as to move to and from the beam, audits upper end is provided with the annular wedge-shaped projection a, which, as the set-screwis moved upward, engages with the serrations t on the under edge of the beam and locks the counterpoise in position. The serrations on the under edge of the beam are made to exactly correspond with the graduating-marks upon its sides, and the circle described by the annular projection upon the set-screw is of a diameterjust equal to 7 5 the distance between somenumber of the serra tions, so that when the counterpoise is locked the projection a will exactly enter the spaces between two of the teeth upon the beam and the index-point 0 will be exactly over one of the graduation'marks. Ifit is found desirable, concentric annular projections may be formed upon the upper end of the setscrew, and thus afford means for making engagement with six or more of the notches on the beam. This construction affords a very simple and convenient means for securing the counterpoise in any adjusted position, and at the same time is so positive in its action that by no possibility can the counterpoise he accidentally o moved. As before stated, this locking mechanism is particularly adapted for use in connection with the various kinds of platform scales; but it may often be used advantageously in connection with hopper and other large 5 scales and with various styles of counter-scales, and in fact with any scale which employs a beam and counterpoisc.

In Figs. 1 and 2 is shown a table, S, of convenient form for holding the scale-weights, the loo tools of the workman, 8:0. Thistable embraces and projects on all sides of the postor column 2 of the scale. It is arranged at a convenient height just below the scale-beam, and is sustained rigidly in position by the brace 1), extending, as shown, from the edge of the scaledeck upward and inward to the posta to which it is attached, and then outward and upward to the under side of the table. This brace not only makes the table firm and secure, but it also braces the post 1), so that it cannot be readily wrenched out of plumb. The table S is provided around its edge with an upwardprojecting piece, r, forming a rim, which prevents articles from rolling or being shaken from the table, and also prevents the table, when made of wood, from warping or being split.

What I claim iso 1. The combination, with the beam having serrations, of the counterpoise provided with the set-screw having upon its abutting end one or more annular projections or teeth arranged to register with or take into said serrations, substantially as described.

2. The combination of the beam having the serrations and the counterpoise cut away, as shown, so as to make the index-point prominent, and provided with a setscrew having upon its abutting end the annular projections or teeth arranged to register with or take into said serrations, substantially as described.

3. A platform scale of the kind described, provided with a table, as S, extending on all sides of the column 1), and with a brace, as b, which extends from the deck of the scale to the column 1), and thence to the under side of the table, thus holding the table firmly in position and supporting the column, substantially' as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
